Exercise during Pregnancy: Developmental Programming Effects and Future Directions in Humans.

Int J Sports Med 2021 Aug 3. Epub 2021 Aug 3.

Human Performance Laboratory, Department of Kinesiology, East Carolina University, Greenville, United States.

Epidemiological studies show that low birth weight is associated with mortality from cardiovascular disease in adulthood, indicating that chronic diseases could be influenced by hormonal or metabolic insults encountered . This concept, now known as the Developmental Origins of Health and Disease hypothesis, postulates that the intrauterine environment may alter the structure and function of the organs of the fetus as well as the expression of genes that impart an increased vulnerability to chronic diseases later in life. Lifestyle interventions initiated during the prenatal period are crucial as there is the potential to attenuate progression towards chronic diseases. Read More

Herbal Nephropathy.

Contrib Nephrol 2021 Aug 3;199:1-12. Epub 2021 Aug 3.

Departamento de Nefrología y Metabolismo Mineral, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico.

An estimated one-third of adults in developed countries and more than 80% of the population in many low- and middle-income countries use herbal and traditional medicines to promote health or for the treatment of common diseases. Herbal medicines can cause kidney damage as a result of intrinsic toxicity, adulteration, contamination, replacement, misidentification, mistaken labeling, and unfavorable herb-drug interactions. The kidneys, due to their high blood flow rate, large endothelial surface area, high metabolic activity, active uptake by tubular cells, medullary interstitial concentration, and low urine pH are particularly vulnerable to development of toxic injury in the form of different syndromes like acute kidney injury, nephrolithiasis, chronic interstitial fibrosis, or uroepithelial cancer.

Aberrant modulation of brain activity underlies impaired working memory following traumatic brain injury.

Neuroimage Clin 2021 Jul 28;31:102777. Epub 2021 Jul 28.

Turner Institute for Brain and Mental Health, School of Psychological Sciences, Monash University, Clayton, Victoria 3800, Australia; Monash Epworth Rehabilitation Research Centre, Epworth Healthcare, Melbourne, Australia.

Impaired working memory is a common and disabling consequence of traumatic brain injury (TBI) that is caused by aberrant brain processing. However, little is known about the extent to which deficits are perpetuated by specific working memory subprocesses. Using a combined functional magnetic resonance imaging (fMRI) and working memory paradigm, we tested the hypothesis that the pattern of brain activation subserving working memory following TBI would interact with both task demands and specific working memory subcomponents: encoding, maintenance, and retrieval.
